How to register for UAE Corporate Tax in 2026: a step-by-step founder's guide

If you've just incorporated a UAE company — mainland, free zone, or offshore — Corporate Tax registration is on your list whether you know it or not. Even if your revenue is below the AED 375,000 threshold. Even if you're a 0% Qualifying Free Zone Person. Everyone registers.

The registration itself is free and done through the FTA's EmaraTax portal at eservices.tax.gov.ae. It takes about 30 minutes if you know what you're doing, or a couple of hours of confused clicking if you don't. This post is the version we wish someone had written before we did it ourselves.

Who needs to register

Every UAE-incorporated legal entity. That includes:

• Mainland LLCs (DED-licensed)
• Free zone companies (DMCC, DIFC, ADGM, IFZA, SPC, RAKEZ, Meydan — all of them)
• Branches of foreign companies operating in the UAE
• Partnerships and civil companies

Sole proprietors and freelancers only need to register if their business income exceeds AED 1 million per year. Everyone else — no revenue threshold applies to the registration itself. You register once and file annually.

The deadline nobody talks about clearly

The FTA published a schedule tying your registration deadline to your trade licence issue date. For companies incorporated in 2024 or later, the rule is simpler:

New companies must register within 3 months of incorporation.

Companies incorporated before March 2024 had staggered deadlines depending on the month the licence was originally issued — most of those have already passed. If you're unsure, EmaraTax will tell you when you log in whether you're inside your window or already late.

Penalty for late registration: AED 10,000. This is a fixed FTA penalty and it's issued automatically.

What to have ready before you log in

Gather these before you start — you'll fight the portal less:

• Trade licence (electronic copy, PDF)
• Memorandum of Association (MoA) — full copy including the shareholder table
• Emirates ID of the authorised signatory (usually the manager or director)
• Passport of the authorised signatory
• Company address — full postal address of the registered office (not just the free-zone name)
• Contact number for the company — the FTA form asks for a landline but a UAE mobile number works if you don't have one
• Business activity codes — these are on your trade licence, but you'll need to translate them into EmaraTax's own dropdown taxonomy (more on this below)

The step-by-step

1. Create or log into EmaraTax

Go to eservices.tax.gov.ae and either create a new account (via UAE Pass or email) or log in.

2. Add a "Taxable Person" profile

You are registering the company as a taxable person, not yourself as an individual. Even though you'll be logged in with your personal UAE Pass, when the portal asks whose details to provide, use the company's details — legal name, trade licence, registered address.

3. Choose the tax you're registering for

Select Corporate Tax (not VAT unless you're also above the AED 375,000 VAT threshold — separate registration).

4. Entity type

For most SMBs the correct choice is UAE Private Company — this covers mainland LLCs and free-zone LLCs alike. You are not a "Qualifying Public Benefit Entity" (those are charities and foundations), and you're not a "Government Entity."

5. Business activities — the tripwire

This is where most first-time registrants get stuck. Your trade licence lists your ISIC-code activities (e.g. 6201.00 Computer Programming). EmaraTax has its own two-level dropdown: Primary Activity → Sub-activity.

In most cases the codes match. In some cases, EmaraTax's sub-activity list doesn't include an option that maps to what's on your trade licence. Common example: a licence with 5820.01 (Software Publishing) but EmaraTax only offers "Gaming Publisher" under the 5820 code, which isn't what your business does.

What to do: Pick the closest matching primary activity, ignore the mismatched sub-activity, and add an additional activity that DOES match cleanly. So if you have Software Publishing on your licence but only Gaming Publisher in the portal, drop 5820 entirely and enter your other activities that map cleanly (like 6201 Computer Programming + 6209 Other IT Services). Your trade licence is the source of truth for what you do; EmaraTax just needs a valid entry that categorises you.

If you have multiple activities on your licence, add all of them. One is marked Primary, the others as Secondary.

6. Fiscal year

The default is the calendar year (January 1 – December 31). If your company was incorporated part-way through the year, your first tax period will be a short one — from your incorporation date to the end of December.

Example: incorporated 3 June 2026. First tax period: 3 June 2026 – 31 December 2026 (~7 months). All subsequent tax periods: 1 January – 31 December.

You can choose a different fiscal year (some free zones default to different cycles), but if you're an SMB with no group structure or complex intercompany dealings, keep it calendar year. It's simpler and matches most of your banking and audit workflows.

7. Contact and address

Enter the company's registered business address exactly as it appears on your trade licence. If you don't have a landline (most free zone SMBs don't), a UAE mobile number is accepted.

For your designation, if you're the founder and the licence lists you as the manager or director, use "Manager" or "Director" respectively. Not "Owner" — the FTA's form doesn't use that term.

8. Review and submit

Double-check the entity name (in both English and Arabic if applicable), the activities list, and the fiscal year. Once you submit, the FTA processes the application and typically issues your TRN (Tax Registration Number) within 20 business days — sometimes same-day.

Save that TRN. You'll need it on every invoice you issue once you cross the VAT threshold, and on every Corporate Tax return you file.

After registration: what happens next

Registering doesn't mean you owe tax now. It means the FTA knows you exist and expects a return.

• Annual Corporate Tax return is due 9 months after your fiscal year end. So if your first short period ends 31 December 2026, your first return is due by 30 September 2027.
• The 9% rate applies to profits above AED 375,000 per year. Below that, your rate is 0% — but you still file.
• Qualifying Free Zone Persons (QFZP) can maintain a 0% rate on "qualifying income" — but this requires meeting specific tests around substance, activity type, and non-qualifying income thresholds. Don't assume you're a QFZP; check the criteria or get an accountant's confirmation before your first filing.

The mistakes we see most

1. "I'm in a free zone so I don't need to register." Wrong. Every free zone entity registers.
2. "I'll register once I'm profitable." Wrong. Registration is separate from tax liability. Register in your first 3 months regardless of revenue.
3. Missing sub-activities that don't match the trade licence. Handle by picking the closest primary activity and dropping the mismatched sub-activity (see step 5).
4. Choosing a random fiscal year to "delay" the first filing. Doesn't work. FTA calculates from your incorporation date regardless.
5. Forgetting the annual filing after successful registration. Registration is a one-time event. Filing is annual. Set a calendar reminder for 9 months after your year-end — or use a system that does it for you.

Never miss another UAE deadline

Corporate Tax registration is one of five recurring federal deadlines every UAE SMB has to track — alongside VAT filings, WPS salary transfers, UBO updates, ESR notifications (where applicable), and trade licence renewals. Miss any one of them and the penalties start at AED 10,000 and go up quickly.

That's what OpeAre solves. Our compliance calendar comes pre-loaded with every UAE federal deadline the day you sign up — Corporate Tax registration, annual returns, VAT quarters, WPS windows, UBO refiling triggers, and your own trade licence renewal date pulled from your uploaded licence. Every deadline sends you a reminder 30, 14, and 7 days out, so nothing lands as a surprise.

Alongside the calendar, OpeAre gives you 11 more modules: AI-reviewed contracts across four models, a UAE-specific contract builder, a policy library with an AI drafter, corporate governance registers (UBO, board, share), KYC/AML workflow, payment approvals, staff training, playbooks and clause library, an AI legal assistant with citations, regulatory update feed, and a signed, exportable audit trail. All in one subscription, built specifically for UAE law.
